Bismuth smithing

In the Steven Universe episode "Made of Honor", Steven explains to Bismuth the revelation that her leader Rose Quartz was also their supposed worst enemy Pink Diamond, that she had faked her shattering the rest of the Crystal Gems were corrupted as a result and that he had unbubbled her without telling the others. When Steven tries making her reappearance a surprise to the others, Bismuth wanders off and drowns her sorrows by working in her forge, making weapons for an army that will never use them because they have either died or were driven mad with corruption presumably because of an idea she had given to Rose.
